Abstract: Clamp assemblies and associated methods are disclosed. According to one aspect, a clamp assembly may comprise a shell, a tensioning mechanism, and a retainer. The shell includes a pair of segments sized to be positioned over a joint connection, with the pair of segments being moveable between an open position and a contracted position. The tensioning mechanism is operable to tighten the pair of segments and includes a threaded shaft extending through a segment opening defined in a first segment of the pair of segments. The retainer is coupled with the first segment and includes a first cantilevered flange configured to engage the threaded shaft to retain the threaded shaft in position relative to the first segment.

Abstract: Compositions and methods are disclosed wherein one or more steroid hormones are combined in a mixture with a sulfur-containing compound. The sulfur-containing compound increases the absorption of the steroid hormone through a mucosal surface, such as skin, oral mucosa, and mucosa of the gastrointestinal tract.

Abstract: An improved process and composition for the extraction of metal from a metal-laden ore, soil or rock is provided. A liquid, three-component aqueous lixiviant comprises water, an alkali metal salt and a low pH acidic composition. A four-component aqueous lixiviant comprises water, a low pH acidic composition, an alkali metal salt and an acid having a pH value less than 2. Both lixiviant compositions are efficient for extracting metal into a pregnant liquid solution. The pregnant solution is treated by known conventional means, such as filtration, centrifuging or electrolysis to remove the extracted metals. The three-component and four-component aqueous lixiviants of the present invention are non-toxic, meaning, not an irritant or deleterious to humans or the environment and perform, as well as, or better than known toxic cyanide lixiviants.

Abstract: A phase-locked voltage controlled oscillator for generating frequency modulated waveforms having a programmable digital RF phase shifter to determine the phase difference between the output signal and a phase corrected reference signal to thereby generate the desired output waveform.

Abstract: A phase locked-loop circuit includes a non-linear voltage controlled oscillator ideally producing a desired output frequency as a function of time and a memory producing signals which add to the phase locked-loop phase error feedback signal to correct for the VCO non-linearities. A calibration circuit upon activation is responsive to the phase error feedback signal for altering the contents of the memory such as to reduce or eliminate the phase error.

Abstract: An inlet for a gas turbine engine is disposed about a curved centerline for the purpose of accepting intake air that is flowing at an angle to engine centerline and progressively turning that intake airflow along a curved path into alignment with the engine. This curved inlet is intended for use in under-the-wing locations and similar regions where airflow direction is altered by aerodynamic characteristics of the airplane. By curving the inlet, aerodynamic loss and acoustic generation and emission are decreased.
